Method for manufacturing nail sticker

Abstract

By manufacturing a nail Sticker with the steps of applying a first coating solution including a mixture of alkyl-methacrylate, hydroxyl methacrylate, and solvent, and a nitrocellulose on the base substrate, heat-treating the product, additionally applying a second coating solution that a nitrocellulose solution dissolved in solvent and a thermoplastic resin gel are mixed and stirred, and heat-treating the product, a nail sticker can be provided, which can be easily-attached to the nail, preserved for a long time, and the remaining portion of which can be easily removed.

1 . A method for manufacturing a nail Sticker, comprising;
 (A) applying a first coating solution including a 30˜50 wt % mixture of alkyl-methacrylate, hydroxyl methacrylate, and solvent, and a 50˜70 wt % nitrocellulose on the base substrate;   (B) heat-treating the product of the (A) step;   (C) applying a second coating solution that a nitrocellulose solution dissolved in solvent and a thermoplastic resin gel are mixed and stirred in a weight ratio of 2.3˜3:1 on a surface of the product of the (B) step;   (D) heat-treating the product of the (C) step.   
     
     
         2 . The method according to  claim 1 ,
 wherein a content of the hydroxyl methacrylate is determined in the range of 0.05 to 0.3 times of weight of the alkyl-methacrylate, and   a content of the solvent is determined in the range of 0.02 to 0.9 times of weight of the alkyl-methacrylate.   
     
     
         3 . The method according to  claim 1 ,
 wherein the (B) step is characterized in that the heat-treatment is carried out based on a temperature of 40˜50° C. for 1.5˜2.5 minutes.   
     
     
         4 . The method according to  claim 1  or  claim 3 ,
 wherein the (D) step is characterized in that the heat-treatment is carried out based on a temperature of 40˜50° C. for 12˜13 minutes. 
 
     
     
         5 . The method according to  claim 1 ,
 wherein the first coating solution includes an initiator having weight of 0.0002 to 0.1 times by weight of the alkyl-methacrylate and a reinforcing member having weight of 0.001 to 0.1 times by weight of the alkyl-methacrylate,   the initiator comprising at least one material selected from benzoyl peroxide and azobisisobutyronitrile, and   the reinforcing member comprising at least one material selected from acrylonitrile, methacrylamide, N-methyl acrylamide, styrene, methyl styrene, vinyl toluene, glycidyl methacrylate, vinyl acetate, monomer including a hydroxyl group such as 2-hydroxyethyl-methacrylate, 2-hydroxypropyl-methacrylate, 4-hydroxybutyl-methacrylate, 2-hydroxy ethylene glycol-methacrylate, 2-hydroxy propylene glycol-methacrylate and etc., or acrylic acid, methacrylic acid, acrylic acid dimer, itaconic acid, maleic acid, and maleic anhydride.   
     
     
         6 . The method according to  claim 1 ,
 wherein a 0.1 to 20 wt % tolylene diisocyanate adduct of isocyanate trimethylolpropane (TDI-1) based on the total weight of the first coating solution is added to the first coating solution.   
     
     
         7 . The method according to  claim 1 ,
 wherein the thermoplastic resin gel includes a thermoplastic resin of at least one material selected from polyurethane, polyvinyl acetate, ethylene vinyl acetate, and polyvinyl chloride resin, and a plasticizer of at least one material selected from dipropylene glycol dibenzoate (DP) and diethylene glycol dibenzoate (DE).   
     
     
         8 . The method according to  claim 1 , further comprising;
 (E) forming a decorative pattern on the surface of the product of the (D) step; and   (F) forming a protective layer on the surface of the product of the (E) step.
